If the S. latifolia did not practice dosage compensation, the expected level of X-linked gene expression in males would be 50% that of females, thus the plant practices some degree of dosage compensation but, because male expression is not 100% that of females, it has been suggested that S. latiforia and its dosage compensation system is still ...
Effective dose is a dose quantity in the International Commission on Radiological Protection (ICRP) system of radiological protection. [1]It is the tissue-weighted sum of the equivalent doses in all specified tissues and organs of the human body and represents the stochastic health risk to the whole body, which is the probability of cancer induction and genetic effects, of low levels of ...
It is still a new field in genetics, but its role in research has already led scientists to uncover numerous explanations for gene regulation. Studying nonsense-mediated decay has allowed scientists to determine the causes for certain heritable diseases and dosage compensation in mammals.
Gain of an X chromosome, [20] Klinefelter syndrome, [21] and XX male syndrome [22] are risk factors linked to male breast cancer. In females, there is no evidence that trisomy X or tetrasomy X females are at higher risk of cancer. [19] Breast cancer and ovarian cancer, particularly more aggressive strains, commonly lack an Xi and have two Xa's ...
The therapeutic ratio in radiotherapy for cancer treatment is determined by the maximum radiation dose for killing cancer cells and the minimum radiation dose causing acute or late morbidity in cells of normal tissues. [13] Both of these parameters have sigmoidal dose–response curves. Thus, a favorable outcome in dose–response for tumor ...
Radiation therapy for a patient with a diffuse intrinsic pontine glioma, with radiation dose color-coded. It is estimated that half of the US' 1.2M invasive cancer cases diagnosed in 2022 received radiation therapy in their treatment program. [5]

Advertisement for a healthy diet to possibly reduce cancer risk. An average 35% of human cancer mortality is attributed to the diet of the individual. [9] Studies have linked excessive consumption of red or processed meat to an increased risk of breast cancer, colon cancer, and pancreatic cancer, a phenomenon which could be due to the presence of carcinogens in meats cooked at high temperatures.
